NOTE: This blog gives a "behind the scenes look" at the progress of the RadeonHD driver's development. As such, its contents reflect the state of the development version of the driver, and not the state of the publicly released version.

The title of this post says it all; compositing for Radeon HD 2000-4000 graphics cards (R6xx-R7xx chipsets) is done. This is another milestone for the RadeonHD driver AmigaOS 4.x. Completion of this major feature puts the support for Radeon HD cards (R6xx-R7xx chipsets) almost on par with the support for the Radeon X1000 series (R5xx chipsets). I say almost because a few of the minor blitter acceleration functions,and DVI and VBlank interrupts are are still to do. As always, there is more work to do. Nevertheless, a composited Workbench performs well with these cards.
